SHE .AF-CARRIER T all whom it 'may concern:

Be it known that I, Ummm M.\n'rn\'- DALE, a citizen of the United States, residing at Manilla, in the county of Crawford and State of Iowa, have invented new and useful Improvements in Sheaf Carriers, of which the following is a specification.

This invention relates to sheaf carriers for binders, the object of the invention being to provide a carrier which shall be simple in construction, and effective in its operation.

The invention consists in certain novel features of construction hereinafter more fully described and claimed.

In the accompanying drawings, Figure l is a top plan view of a. sheaf carrier constructed in accordance with the present in- \ention, illustrating the same in applied position upon a binder, the binder beingl indicated by the dotted lilies. Fig. 2 is an enlarged longitudinal sectional view upon the line Q-Q of Fig. l, illustrating the sheaf or supporting fingers in closed position. Fig. 3 is a similar view illustrating the she-af supporting fingers in their opened position. VFig. l is a. transverse sectional view upon the line l-f of Fig. l, the figure being-en lai-ged.

The improved sheaf carrier is adapted to be applied to harwsters and binders of any ordinary construction and comprises a rectangular' frame 1 carrying a pair of spaced pivoted axles 2 and Secured to these axles 2 and E3 are the shcaf supporting fingers -Lt and The axles 2 and are each provided with oppositely extending ears or offsets 6 and 7 adapted for the reception of a connecting rod 8.

By reference to the several figures of the drawings in will be noted that the ear G connected to the axle 2 extends below the said axle and that the ear T connected with the axle extends above said axle so that upon the rotation of one of the shafts the rod 8 will canse the opposite axle to rotate in an opposite direction, thus causing the fingers' t and 5 t0 open away from each other. The ear 6, it will be noted by reference to the figures of the drawing is of a greater length than the ear 7, and the supporting fingers el carried by the axle 2 are also of a greater length than the fingers carried by the axle 3. The fingers Ll are. suitably inclined to provide means whereby Specification of Letters Patent.

the sheaves upon the device may be easily slid therefrom toward tbe side of the machine when the carrier is in its open position as illustrated in Fig. 23, and the fingers 5 are also suitably bent to provide a substatitial retarding means for the sheaves dropped by the fingers el, so that when the device is operated the sheaves drop in a compact mass providing a substantial shock.

By the construction of arms or lingers as above described, it will be noted that the longer fingers -lare iii-might more closely toward the ground than the fingers 5 when thc device is operated, and consequently are more liable to contact by stones or other obstructions than the shorter fingers 5. In order to prevent the breaking of the fingers by such contacts. l have provided the fingers with a forwardly ex'tending portion projecting from beneath the axle 2, and this portion is provided with an offset lprojecting upwardly and connected with a transverse bar t). rl`his bar 9 has its end adjacent the connecting rod 8 provided with a suitable perforation. and the axle f2 is provided with a projecting finger or offset it). The perforation provided by the bar t) and the oltset l( are adapted for the reception of a tension spring il. 'lhis spring il is adapted to retain the fingers 4 in a parallel plane with the longitudinally extending fingers 5 and is also designed to provide means for relieving the fingers of shock when contacted by an obstacle.

rThe axles 2 and 3 are cach provided with vertically extending offsets i2, and these offsets are adapted for pivotal connection with the arms 13 and illof the locking device. The arms 13 and tl are pivotally connected together as at 15 and the arm lat is provided with an extending finger ,ifi which is adapted to contact and be engaged by a headed pintle I7 carried by the arm i3. By this construction it will be noted that when the arms 13 and 141 are in their locked position, as illustrated in Fig. 2 of the drawings, the supporting fingers are retained normally closed, but when one of the arms is contacted to throw the pivoted members upwardly as indicated in Fig. 3 of the drawings the supporting fingers 4 and are swung open. In order to operate the locking member I have provided the side of the frame l adjacent the arm 3 with a suitable opening adapted for the reception of an offbreaking Vthe joint provided by the linger 16 and the headed stud 1.7 and swinging the lingers and 5 to their open position.

ln order to automatically close Vthe lingers t and 5. when pressure has been released troni the olle-et arin 18. l have provided the unclertace of the axle S with a suitable eye 19, adapted for the reception of a tension spring 20. This spring Q0 has its opposite end conn ted with a suitable staple 21 proA one or' the sides or" the traine 1.

ec 1moed upon a 'l that By this i" ingeinent it will be noter. the lingers and 5 will be automatically closed through the inediinn of the spring 20 when pressure is released troni the elenient 18 and that the twins 18 and lil will be effectively locked so as te prevent the revolving' or" the axles and 3 and thus retain the lingers l and 5 in their closed position while receiving the sheaves.

ilfhile l have illustrated and described the preferred einbodiinent of thev invention it now appears to nie, it is to be understood that ininor details ot construction within the scope of the following claiins may be resorted to withoutdeparting from the spirit or sacrificing any ot' the advantages ot the invention.

llaving thus 'fully described the invention what is elaiined as new is:

1. The combination with a rectangular traine, a pair ot horizontally arranged axles .secured between two sides of the traine,

lly inclined lingers upon the axles,

downwar( the lingers extending toward and terininating in a line with each other and the fingers carried by one of the axles being of a greater length than the lii'igers carried by the opposite axle, ears upon the axles, a locking de vice comprising a` pair otf arnis pivoted together and connected with the ears and normally adapted to prevent the axles troni rotation, and nieans for breaking the pivoted joint otl the arins to rotate the axles and the lingers carried by the axles.

rllhe combination with traine, a pair ot' spaced axles upon the traine, curved lincarried by the axles and extending` toward the axles,

l l l l l l a connecting rod between l by the axles.

the axles, a latch ineinber for the axles to nornially prevent the axle from rotating, said latch comprising a pair of pivoted arins, one of said arins being' provided with a finger, the opposite arni being provided .vith a headed stud adapted to engage the linger, and means lor swinging one of the arins upwardly to disengage the linger from the headed stud to rotate the axles and to swing open the lingers carried by the axles.

The. combination with a rectangular traine, a pair ot spaced axles horizontally connected with two of the sides of the traine, downwardly curved lingers carried by the axles and projecting toward each other, a connecting rod between the axles, olisets upon the axles, a pair oi locking arins pivotally connected with the olfsets of the axles, a "toot opera-ted device for unlocking' the axles, and a resilient nieniber connected with one ol the. axles to return the lock and axles to their initial position.

4. The combination with a traine, a pair of spaced axles upon the traine, curved lingers projecting' toward each other carried the lingers of one of the axles being longer than the lingers of the opposite axle andsaid lone'er lingers beinO rovided 7 b Q D with extending portions each having an 0H"- set extension, a transverse bar connected with the olilset extensions, a linger upon the axle, a tension spring connected with the linger and secured to the transverse bar, a connecting' rod betweei'i the axles, laterally7 extending ears upon the axle, a latch ineinber 'tor the ears. said latch ineniber coinprising a pair of arins pivotally connected together and pivotally connected with the ears of the axles, one of said arnis being' provided with a projecting linger, the opposite arin being provided with a headed stud adapted to engage with the linger to sustain the arias in norinal parallel plane, ineans for swinging one oit the arins to release the linger troni the headed stud and for rotating the axles to swing the lingers carried by the axles open, and a resilient ineinber connected with one ot the axles and the Jtraine for retaining the lingers, axles and latch nieinbers to their norinal position.

ln testimony whereof I allix iny signature in presence of two witnesses.
